Field detection of 2,4,6-trinitrotoluene in water by ion-exchange resins

摘要

A method and a device for the detection of trinitrotoluene (TNT) in effluent water from the purification apparatus of ammunition plants is described. The tube detector utilizes a basic oxide section to convert the TNT to its Meisenheimer anions, followed by an alkyl quaternary ammonium chloride ion-exchange resin which collects the colored anions. The length of the resultant stain is proportional to the concentration of TNT in the water.
